Many efforts have been made to use waste glass in concrete industry as a replacement of coarse aggregate, fine aggregate and cement. Fly ash is generated in huge quantities every day in major thermal power stations of India. The safe disposal of this fly ash is the major socio-economic problem before the authorities and is becoming a costly affair for them. Conventional method of concrete broad construction consumes the natural resources like stone metal, sand, murum, etc. And causes ecological imbalance the use of fly ash in concrete road construction will save such resources. A part of cement can be replaced by good quality fly ash and glass powder to the extent of 0-30% & 0-15% respectively. This wood results in lowering cost of resultant concrete without any loss in strength. The use of fly ash will solve the disposal problem and automatically reduce the construction cost .Because of the use of fly ash; rigid pavement behaves as a semi rigid pavement causing substantial reduction in cost of construction. If the fly ash is utilized on large scale for road construction, the infrastructure development can be completed at lesser cost and will also help for environmental protection of our country.A series of tests were conducted to study the effect of cement was replaced by glass powder (0%,5%, 10% and 15%) & fly ash (0%, 10%, 20%, and 30%) on compressive strength and durability.Hence our project aim is to evaluates the strength of hardened concrete, by means of partly replacement of cement with glass powder and fly ash design for M25 grade of concrete by preparing of concrete cubes & cylinders have been tested at the age of 7, 14 and 28 days with steady water curing situation. . The particle size effect was evaluated by using glass powder of size 600μm-100μm.The results showed that the maximum increase in strength of concrete occurred when 10% replacement was done with glass powder.
